A number of new 3,7-disubstituted pyrazolo[3,4-c]pyridines have been designed and synthesized from suitable 2-aminopyridines. The antiproliferative activity of the derivatives was determined against the pancreatic MIA PaCa-2 and ovarian SCOV3 cancer cell-lines. IC50values of the most promising analogue 46 lie in the submicromolar or low micromolar range. Furthermore, compound 46 shows similar inhibitory activities against DU145, A2058 and PC-3 cancer cells, blocks the cell cycle at the G0/G1phase and induce apoptosis, as determined by the appearance of apoptotic nuclei.

A series of pyrazolopyridines has been prepared by nitrosation of 3-acetamido-4-methylpyridines and subsequent rearrangement and cyclisation of the N-acetyl-N-nitroso-compounds produced.The reactions of the pyrazolopyridines have been investigated. 1- and 2-Acetyl and 1- and 2-benzyl compounds were obtained and their structures elucidated spectroscopically.The ring system readily undergoes electrophilic substitution in the 3-position. 7-Chloropyrazolopyridine has been shown to be more susceptible to nucleophilic substitution than the isomeric 5-chloro-compound.
